To all whom it may concern,

Be it known that I, EDWARD ERICKSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Oementing-Machines, of which the following is a specification.

This invention has relation to machines for applying cement or like material to a surface to be coated therewith. In the man ufacture of shoes, for instance, it is desirable to cement the upstanding channel flap of a sole to the face thereof, and while my invention relates more particularly to machines for coating such surfaces with cement, yet it is applicable for machines to be used in other connections.

The object of the invention is to provide certain improvements in machines of the general character referred to, for more perfectly controlling the feed of the cement, preventing wastage thereof, and insuring its proper application to the surfaces to be coated.

In addition the invention has for its object to provide for positioning the work with respect to the brush, and for feeding the work, and for generally enhancing the efii ciency of such'machines.

Referring to the drawings which illustrate one embodiment of the invention, Figure 1 represents a side elevation of a cementing machine. 'Fig. 2 "represents an enlarged front view of the upper portion thereof.-

Fig. 3 represents a longitudinal vertical section therethrough. Fig. 4 shows the position of the combined gaging and feeding device. Fig. 5 illustrates the gearing which actuates said gaging and feeding device.

On the drawings, indicates an upright stand having at its upper end a tubular clamp 11 in which the supporting column 12 for the head ofthe machine is mounted. The column may be conveniently provided with a laterally extended upper end to form a table 13 toreceive the head. The stand and the column constitute a vertically extensible and contractible support or frame for the head on which the operative parts of the machine are mounted.

The head of the machine consists of a tank or supply reservoir 14, which has anopening in the top through which cement may be introduced therein, and the opening may be normally covered by any suitable closure Specification of Letters Patent.

as indicated in dotted lines; The sides of the tank converge at their lower ends as shown in Fig. 2, so as to guide'all the cement toward the outlet 15 therefrom. The tank is formed with a base 16 which rests upon the table 13 and which is removably held thereon by hinged bolts or clamps 17. Below the chamber in the tank there is a cylindrical pump chamber 18 which extends from front to rear of the head and which communicates with the interior of the tank through the port 15'. The tank and the chamber constitute a cement receptacle. The rear end of the chamber 18 is closed by a cylinder head 19, the front end being Shown as closed by a head or wall 20 cast integrally therewith. Arranged in the pump chamber is a screw conveyer or pump 21, of which the shaft 23 is journaled in the heads 19 20. The rear projecting end of the shaft is provided with fast and loose pulleys 121 122 or other suitable powertransmitting device. At the rear end of the screw is a peripheral flange 22 close to the head .19, to prevent the access of cement to the bearing for the shaft.

The screw conveyer or pump forces the cement which flows into the chamber from the tank into the device by which it is applied to the worln Attached to the end or head 20 of the chamber 18 is a bracket or casting 25 having forwardly extending arms 26 27 in which is journaled an upright hollow shaft or sleeve 28. The arm 27 serves as a support as well as a bearing for the sleeve 28, which, as will be explained, is the brush holder and actuator. Upon this sleeve is secured a small bevel gear 29 which intermeshes with and is driven b a bevel gear 30 secured to the forward re uced end of the shaft 23 which extends through the bracket 25 as shown in Fig. 3. The lower end of the sleeve is formed with an internally threaded socket 31 and with a peripheral flange or upper face by which it is held against theface on the frame 27 by a. collar 32 which is screwed upon an annulus on the said frame. Immediately above the arm 27 is a packing ring 33 with suitable packing. The arm 27 is formed with a small-chamber or cementreceiving reservoir 34 which communicates by a duct 35 with the chamber 18. This duct extends through the arm 27 and through the head 20. The lower end of the sleeve 28 is illustrated as somewhat enlarged, and it is formed with apertures 36 which afford a communication between the interior. of the :hollow shaft or sleeve and the-.chamberfit. Secured into the socket in the end of the hollow shaft or sleeve, is the shank 87 of a brush.- The said shank is formed with an externally threaded bossonwhioh-"is secured a tapered shell orcasing 38 for'forming a cement receiving chamber or cavity 39, into which the cement ma ass through a duct $0. The shell or casing 38 has a'transverse partition 4L in the center of which is secured a tube 42. Within the shell and around the tube 42 are secured a. plurality of bristles, as at 43, the bristles extending some little distance beyond the lower end of the tube 42. As thus described, the brush is formed with a reservoir for the cement with-bristles for the applicationof the cement, and with means, as a tube, for

conducting the cement to the middle of the mass of bristles. A. valve is utilized to con-' trol thefiow of cement into the brush. This valve is illustrated lat-44. and its conical end.

isadaptedto be-seated in the upper end of the shank of the-brush. The valve fitsv with in the hollow shaft and in the. iposition shown in. Fig. 3, it prevents the passage of cement from the: small chamber 34 into the hollow shaft, and from the hollow shaft into the duct 40. The valve stem 45 passes upwardlyithroughthe hollow shaft and'is pro-ivided with a spherical knob or head 46 which is socketedin the cup-like end 47 'of a lever 48 fulcrumedbetween sits ends upon a stud 49'passed into the wall of the tank. A spring 50 has-one end attached to the free end of the lever andits other end attached to-a: hook 51 on the exterior of the tank, and it tends to swing the lever about its fulcrum so as-to hold the valve. against its seat to cut 0E thefsupply .of cement to the brush. The free endof the lever is connected by a chain or other suitable form of connection 52 to=a foot treadle.-53-.fulcrumed at 54 at the base of the-frame-IO, so that the operator may open the valve to the desired extent. I fin-proximity to the brush, I, provide a workgage-55-which isiadaptedto rotate. As shown, it is-in the form of a frusto-cone' and-- it :tsxnounted upon a shaft 56. This shaft is journaled near its 'ends'in'bearings 57 58, formed uponthe ends of an elongated yoke or support69. The said support is located between ears 60 which project forwardly from the arm 27 of the bra-cket25 .-and it is-provided with a curved slot 61 to receive-a pin 62apassed through said cars '60. The upper end-,of the supportis provided with'laterally'extending pins 631 which are seated in hooks t4 projectingvforwardly. from the -arm of the-bracket-25. The shaft '56 is arranged substantially in parallelism with the hollow shaft 28-and it is held yieldinglyfidownward by a spring tii'i so" that the gagelis normally in a plane below the plane of the alienate end of the brush, as shown in Fig. 1. When so located,.the work may bebrought against the gage with the edge of the age under or against the upturned channel, ap c0,- and the work engaged and bodily lifted to bring the work into position to receive the cement from the brush as illustrated in Fig. 4. The

gage may be well utilized for the purpose of feeding the work and to this end ll secure to the upper-end of: the shaft 56, a gear wheel 66. An elongated ear 67 is secured to the upper end of the ho low shaft 28.. When the gage is in the position shown in Fig. 1, the gears are out of mesh, but when the gage is; lifted into the position shown in Fig. 4, the gear 66 is caused to intermesh with the gear. 67 to effect the rotation of the shaft 56, and therefore of the gage 55. To assist the intermeshing of the gears the ends of either teeth are beveled or pointed as shown in Fig. 5.

In order that the cement ma .escape from the conveyer-chamber, when t e valve 44 is seated, I provide. a port or by-pass leading from said chamber to the tank near the front end of the chamber, this port being relatively small as compared with the port 15 so as not to interfere with the feeding of the cement when the valve is open.

i The yoke-59 has the elongated slot 61, as. hereinbefore described, so that the gage and work feeding device has a limited movement transversely of the-brush, for shoes havingchannels of difierent widths.
